| At present, the diesel motor vehicle not only has good power and economy, but also has the advantages of energy saving and environmental protection, thus have been widely used in countries around the world. However, major pollutants discharged in exhaust gas of the diesel motor vehicle, such as particle matter (PM), nitrogen oxides (NOx), carbon monoxide (CO) and hydrocarbons (CH), have great pollution on the urban environment and generate serious harm to human health at the same time. In exhaust gas post-treatment technology, diesel particulate filter (DPF) serving as a most effective and practical method for eliminating PM in the exhaust gas of the diesel vehicle is widely used in a diesel vehicle exhaust gas treatment device, but a noble metal catalyst is required to be coated on the inner wall of the DPF, and the noble metal resources are becoming scarce and expensive. LaMnO3 with perovskite structure has higher catalytic activity because the A position part is replaced, thus has become a research hot topic of the diesel vehicle catalyst. |
